AC motor 2,5 A | Temperature humidity control | 5 steps

Transformer fan speed controller with Modbus RTU communication for manually or demand-based fan speed regulation. The supply voltage ranges from 115 to 230 VAC. It is used for single-phase motors. The maximum motor current (combined) is 2.5 A. Modbus communication is used to control the RTVS8 serie. The fan speed is controlled by gradually varying the motor voltage. The autotransformer technology produces a perfect sinusoidal motor voltage. This ensures that the motor runs quietly. The electrical noise from the autotransformers is reduced by a special impregnated coating. To adjust the requested fan speed a potentiometer (SPV series), Modbus I/O module, or BMS system can be used. The fan speed can also be adjusted based on the temperature, relative humiudity, CO2 and air quality (TVOC). Surface mounting is possible (IP54 protection).

A room transmitter can measure ambient light levels, relative humidity, and temperature. The distinctive enclosure accommodates flush or surface mounting. The supply voltage is 24 V DC. The sensor algorithm controls the single analogue output based on the measured values. This one output can be used to directly control an EC fan, an AC fan speed controller, or a damper actuator. There is a choice in output format. All measurements and the output value are accessible via Modbus RTU. The ambient light sensor can be used in a variety of applications to control the ventilation system based on the amount of people present in the room. Adjustments are possible for every setting with Modbus RTU. The light levels of the LEDs used for status indication are also programmable. This HVAC sensor is frequently used to regulate humidity and temperature in data centers, museums, wine cellars, etc.
